I think most people (myself included) make an estimate of ERP/EIRP and declare that, rather than TX power. After all, it is only the radiated power that counts as far as the receiving stations are concerned, and with huge differences between efficiencies of different stations' LF/MF antennas, the transmitter output by itself does not tell you much about what is being radiated. But the norm for HF WSPR seems to be to quote TX output power - probably reasonably similar to the radiated power on those bands, at least when simple antennas are used. Cheers, Jim Moritz 73 de M0BMU
